ABSTRACT:
Fifteen compds. R1R2R3CN(OX)CR4R5R6 (X = a group having .gtoreq.1 C and is such that the free radical formed by cleavage of the O-X bond is capable of polymg. unsatd. monomers; R1, R2, R5, and R6 = alkyl or substituted alkyl of sufficient length to provide steric hindrance; R3 and R4 = alkyl, substituted alkyl, or a group which completes a cyclic structure contg. the N atom) are prepd. and used as initiators for the polymn., including block and graft polymn., of unsatd. monomers. The initiators permit control of the growth steps of polymns. to produce oligomeric polymers. Thus, a soln. of 400 mg di-tert-butyl nitroxide and 234 mg di-tert-Bu peroxyoxalate [1876-22-8] in 5 mL styrene [100-42-5] was heated 2 h at 50.degree. to prep. N-(2-tert-butyl-1-phenylethoxy)-N,N-di-tert-butylamine (I) [96724-60-6]. A soln. of 52 mg I in 3 mL Me acrylate was heated 0.5 h at 100.degree. to prep. 0.42 g polymer Bu3OCH2CHPh[CH2CH(CO2Me)]25ON(CMe3)2.
